An Organic Puzzle Using Meldrum's Acid
R. David Crouch and Michael S. Holden
Department of Chemistry, Dickinson College, Carlisle, PA 17013-2896
Cover
April 2002
Vol. 79 No. 4
p. 477
Abstract
Meldrum's acid or 2,2-dimethyl-1,3-dioxane-4,6-dione undergoes a Knoevenagel condensation with formaldehyde to form an active Michael acceptor for a second molecule of Meldrum's acid. The structure of the resulting product is determined by correlation of the products of possible reactions of Meldrum's acid and formaldehyde with the NMR spectrum of the product.
Supplement

Notes for the instructor, a handout for students, and some sample spectra are available.
